Abstract
A new series of hydrazinecarbothioamides 6-9 bearing 5H-dibenzo[a,d][7]annulene moiety were synthesized. Cyclization of 6-9 in NaOH solution produced the corresponding 1,2,4-triazoles-3(4H)-thiol 10-13, which proved to be axial isomers. The thioethers 14-17 were prepared by alkylation of 10-13 with methyl iodide. All new compounds were characterized by elemental analysis, IR-, UV-, 1H-NMR and 13C-NMR spectroscopy. The evaluation for antimicrobial activity against Staphylococcus aureus ATCC 25923, Pseudomonas aeruginosa ATCC 27853, Escherichia coli ATCC 25922, Bacillus subtilis ATCC 6663, Salmonella tiphimurium ATCC 14028, Shigella flexneri ATCC 12022, Candida albicans ATCC 90028 was performed.
